4. Leave cabinet doors, bed doors and wardrobe doors slightly open at flight to allow
circulation of air in and around all furniture components
5. Use propylene glycol type antifreeze in waste and drain water tanks to prevent
freezing. Quantity of antifreeze needed will vary with ambient temperature and the
amount of liquids in tank.
6. For extended stays in cold weather, insulate the water line outside the motorhome.
You should remember that low temperatures in combination with high winds cause
an equivalent chill temperature much below what your thermometer is reading. For
instance, with an outside temperature of zero degrees, and the wind velocity of 10
miles per hour, the equivalent chill temperature is minus 20’ F. The exterior water
faucet has an in-line valve inside the motorhome. In below freezing temperatures,
shut off the valve inside and open the exterior brass valve so it will drain.
WARNING : Always shut off the LP gas when gasoline is added to the
fuel tank.
Some states do not allow LPG to be turned on while moving. While traveling in these
states you must use your common sense. How cold is it? How long will it be before
you can turn the heat back on? Is the temperature dropping or rising? Remember, the
wind chill factor when driving 50 MPH will cause the interior of the motorhome to cool
much faster than when it is parked.
